IMPROVEMENT IN ENVELOPES.

At t may be made,iextendi h,- or an angular piece at i; while'the ends so as to form any desired angle with the folding-lines. The essential requisite of any form, however, is, that it shall permit the flaps to be folded down snugly upon the front A. The back B of the envelope is also formed with an angular projection, K, which corresponds in size with the projection F after the flaps G have been folded down. The outline of the envelope having been thus produced the flap K is folded down upon the front A, along the line m, and the flaps G along the lines h. The back Bis then folded down upon the'front, as previously described, and securely pasted or otherwise fastened to the closed without diminishing the size of the envelope described in cutting, which would be the case if the flaps K G were omitted and the back and front fastened to each other at the ends between the lines h m. The flaps also afford a secure connection for the front and back, and prevent them from being casually separated or torn apart.

By this construction an angular projection is formed upon one end, which can be readily torn or cut'oif to open the envelope without cutting or tearing its contents, because the latter does not extend into the projection.

To facilitate the opening of the package by tearing off the projection, one or more straight 'or curved rows of perforations, a, may be formed in the latter, as shown in the drawing, Fig. 2, although this is not absolutely necessary.

If desired the flaps G G may be omitted in the formation of the envelope, in which case the points of the front A and back B are pasted together outside of the line 0, while the flap O at that end terminates at the shoulder 1), as shown in Fig. 3. By this form the projection is made without diminishing the size of the envelope, because the square pocket is equal in length to the length of the flap O. l

A still further modification is shown in Fig. 4, in which the end is truncated and extended 2 135,819 beyond the flap O and square pocket, the age without injuring the contents of the latbevelsq being formed at any desired angle. a ter, substantially as described.

The projection may be formed upon the side RICHARD K. KUHN. as well as the end of the envelope, or upon THOMAS O. ATKINSON. both ends and at any angle or deflect-ion Witnesses to R. K. KUHN:
